This is the fourth and current Eon in Earth’s history. This Eon marked the biggest changes in Earth’s history ever. It introduced complex and new lifeforms such as Trilobites, Ammonites, Horseshoe Crabs, Dinosaurs, Birds & Reptiles, Insects, Mammals and Humans. Many changes and extinction events happen in this Eon, both good and bad.

Climate
The climate in this eon was very well, better than the Proterozoic and Archean Eons. However, in the recent Cenozoic Era, global warming and climate change has been occurring due to human activity.

Life
Life has flourished in this eon, from trilobites, to dinosaurs, to humans. All have contributed (except humans) in a way.
